1 Claim.

This invention relates to devices designed to discharge fluid or creamy matter in certain quantities on each operation.

One of the objects of this invention is to provide a lotion dispensing device from which a certain amount will be discharged upon the insertion of a certain coin by which an operating mechanism can be engaged to result in such a discharge.

Another object is to provide a mechanism by which the operation of the device is controlled against more than one full movement on each insertion of a coin.

Another object is to provide a control against 15 a further discharge on each return to the original inoperative position.

Other objects will appear from the following description and appended claim as well as from the accompanying drawing, in which:

, Fig. 1 is a side elevation of the dispenser embodylng this invention, partly in section on line l-i of Fig. 2, and otherwise broken away to show inside details.

Fig. 2 is a cross section on line 2-2 of Fig. l.

As illustrated, the outside operating knob 3 is mounted on a plain pin ii and free to move back and forth against the tension of the spring 5 without affecting any of the other mechanismsl inside of the dispenser housing 6.

.. For dispensing any matter from the device, a plunger l is disposed in the housing S movable in a direction parallel to the pin li, against the tension or the spring t, and shiitable in a control cylinder 9.

A conduit lil maintains a communication between the cylinder 9 and the container il. This container in this case is illustrated as of transparent material, such as glass, though it may as well be of any other material, however, glass or the like being preferred since observation as to the amount contained therein is made easier and desirably attractive. A central bolt l2, secured in the top of the housing t, extends upwardly to near the top of the container, a nut i3 set against 5 a washer lli over the top of the container ll holding the container suitably sealed to the top i the housing ll. The cap l5 closes the top of the container, and allows a relling of the container.

Another communication is provided by way of a second conduit I between the cylinder 9 and the faucet il, by which a certain amount can be discharged on each operation of the plunger '1, against the check-valve I8.

When the plunger 'l is in its normal inoperative position, any matter contained in the container Il can enter and ll the cylinder 9 by way of the conduit I0, for which a communication is left free by the plunger in this position.

As soon as the plunger is moved into the cylinder, however, the communication through the conduit is shut off, and the matter trapped in the cylinder is forced through the conduit it past the check-valve il, to discharge through the faucet I'l, on a continued inward movement of the plunger.

To prevent repeated partial movements of the plunger, a catch mechanism is provided in the housing, consisting of a double lever, one leverarm i9 extending to a point to come into engagement with the operating pin il, and another leverarm 2i? extending to a point to come into engagement with the plunger l.

An interengagement is procured between the operating pin Il and the plunger l by shoulderrings or flanges spaced and arranged in such a manner that a suitable coin or operating member will become wedged between such flanges or rings under certain conditions.

Through the coin-chute 2|, a coin or operating member may be dropped until it comes to rest on the pin 22, provided so as to project laterally from the iront wall of the housing inwardly.

A flange or ring 23 is provided on the operating pin ll so that it will engage the coin or operating member by a contacting from one side near one edge; while a double flange 2&-25 is provided on the plunger in such a manner that the operating member will become wedged in the double ange when the operating member is contacted and pressed by the operating-pin i by means of the ilange 2(3, the wedging being on the opposite edge of the operating member with respect to the edge contacted by the liange 23.

The dotted lines 26 in Fig. 2 indicate roughly the position into which the operating member first drops when it comes to rest on the pin 22 after having dropped through the chute 2l while the dotted lines 26a indicate the position into which the operating member becomes wedged when contacted by the operating pin 4 by means of its flange 23, the operating pin 4 being moved in the direction of the arrow 2l while the plunger has a tendency to resist under the tension of the spring 8 in the direction of the arrow 28, resulting in such wedging.

The lever-arm 26 of the catch-mechanism is provided with catch-hooks 29 and 30, the hook 29 serving to engage the ilange 25 after a short inward movement of the plunger so that, if the operating pin 4 were released to the slightest extent, the operating member will be released from its wedged position and drop into the bottom of the housing, thereby making it impossible that the plunger can be moved repeatedly for partial movements without an insertion of new operating members.

The second hook 30 of the catch-mechanism serves to hold the plunger after having been pressed into the cylinder fully, and the plunger is retained in this position until the operating pin 4 is released fully until the lever-arm I9 comes into contact with the flange 23, thereby releasing the plunger from the hook 39, the engagement by the hook 30 also serving to hold the plunger suiciently to release the operating member as soon as the operating-,pin is released to the slightest extent after the plunger has been pressed into the cylinder fully. The spring 3l serves to hold 20 the double-lever l9-2'3 under suitable tension to operate as described above. l

Having thus described my invention, I claim: In a dispensing device of the class described, a

plunger member mounted for axial movements and having a laterally projecting shouldered portion, an operating member also mounted for axial movements but parallel to the axis of the plunger member and also having a laterally projecting shouldered portion in a position to normally pass the first-named shouldered portion when the operating member is moved axially, one of the shouldered portions being in form of double flanges spaced so that a control member will readily drop in but become wedged at one edge when tilted and the other shouldered portion being disposed to engage the opposite edge of the control member for tilting it when the operating member is actuated, and a catch having one contact member to become engaged with the shouldered portion of the plunger member and having another Contact member to release that shouldered portion whenever this other Contact member is in contact with the shouldered portion of the operating member in its inoperative position.
